HOT-WATER BOTTLE.

Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed September 18, 1911. Serial No. 649,827.

To all whom it may concern:

Be it known that I, Anrnoxso S. CAMP- BELL, a citizen of the UnitedStates, and a resident of Medford, in the county of Middlcsex, State ofMassachusetts, have invented an Improvement in Hot-lVater Bottles, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like characters on the drawingsrepresenting like parts.

This invention relates to hot water botties, and among other objectsprovides a hot water bottle which is more durable than those heretoforemade and which has an increased field of usefulness.

The character of the invention may be best understood by reference tothe following description of an illustrative cmbodL merit thereof shownin the accompanying drawing, wherein:

Figure 1 is a side elevation of an illustrative hot water bottle shownherein as embodying the invention; Fig. 2 is a ,vertical section takenon linoQ- l of Fig.1, Fig. 3 is a. partial View similar to Fig. 2,showinga device which may be used in connection with the bottle; Fig. 4shows a protecting sleeve which may be used on the bottle.

Referring to the drawing, the illustrative hot water bottle there shown.comprises a container or body 1, of copper or other suitable material,which may have its exterior" surface nickel-plated or otherwisefinished, as desired. Thiscontainer preferably has the form of an oblatespheroid, although it. will be understood that it may have other shapesif desired. As shown herein the container is foianed of two opposeddished plates 3, 5, one of said. plates having a cir cumferential flangeTembraced by, and soldered or otherwise secured to a corresponding lip 9on the other plate. 1

To provide a hapdle for positive manipulation of the conta ncr l-as morefully hereinafter described, and to ermit the connd emptiedconveniently, a neck 11 'is pro ided, soldered or otherwise made rigid wth said container. 1.

An important to ture ofthe invention relates to t e constru tion'of thishandle neck,

whereby it is ma' tained cool to prevent discomfort to the user inholding; and manipulating the same. To this end the neck comprises anouter wall or sleeve 13 and aninner wall 15, spaced sufficiently toprovide a substantial chamber 17 between them. It will be observed thatthe hot water in the container is in contact merely with a portion ofthe inner wall 15 and does not contact with the outer wall 13, the partwhich is in immediate contact with the hand. Said chamber 17 constitutesin etlcct an insulation, which prevents the heat from being transmittedfrom the container to the wall of the neck grasped by the hand. Torender this chamber still more etli'cctivc as an insulator, the outerwall 13 may be provided with a plurality of rent holes 19 distributedtherein at suitable intervals. These holes will permit the air tocirculate. freely to and from. the chamber 17 and tend to make thetemperature in said chamber equal that of the outside air. The neck maybe provided with a usual stopper 21 threaded to the lower part of theinner wall 15, said stopper having: an annular gasket 23 adapted forsealing engagement with an internal flange 25 on said inner wall 15.

To prevent the hand from sliding into -ontact with the hot body of thecontainer the neck may be formed with an annular rib or shoulder 26 atthe juncture of said neck with the body of said container.

'The body of the container 1 will of course be subjected to considerabledifferences of temperature, and being); composed of metal may expand andcontract more or loss and cause-the dished plates 3 and 5 to spread orapproach more or To take care of such expansion and contraction and -tosti'tlcn these plates and prevent any collapsing thereof in use, stayingmeans is provided.

As shown herein, this means comprises tubes 27 and 27' having pressuredistributing flanges 28 at their bases soldered or otherwise secured tothe plates 3 and 5 respectively, one of said tubes being suilicientlysmall 1' than the other to telescope into the same with a free slidingfit. To provide a stay which will be responsive to the expansion andcontraction of the plates and always tend to maintain them in a properspread position, a helical spring 31 is introduced into said tubes andis confined by contact hot water bottle described is for hot massagingor ironing purposes. It 'is admirably adapted for thisuse since thecurved 4 contour offered by its oblate spheroid shape permits it to bereadily appliedto and conform with various parts of the human body. Itsmassaging movement'or manipulation may be easily controlled merely bygripping the bottle by its cool handle neck. This ready -control is duelargely to the rigid connection of said neck with said container; thenon-iiexible or rigid sides of the container; and to the fact that thecontainer in its overall length is comparatively small and within shortradius from said handle so that it not at all unwieldy.

To permit the back, or parts of the human body which are notconveniently" accessible, to be massaged, the bottle maybe provided withan extension handle 33 (Fig. 3). When-this handle is employed, it willbe substitutedi'or the stopper 21 described, and is provided with.athreaded stopperlike end 35' for this purpose. The handle may terminatein a knob 37, which together with the rim of the neck 11 will offershoulcasing.

ders for engagement with the hand, facilitating the manipulative controlof the bot-- tle.

To provide abetter'. grip on the neckll of the bottle and furtherprotect the hand of the user, there may be provided a sleeve 39- (Fig.&)of rubber, asbestos or other;=suitable material. having a collar 4L1overlyi g the portion of the container adjacent said neck.

In some uses it may be desirable to pro 'vide a soft exterior surfacefor the body.

To this end there may be employed acasing 42 (Fig. 1) of flannel, fabricor other suitable material shaped tofit and receive the container. Tohold the casing onto the container it may be gathered at one end andtied about the neck of the container by a cord or elastic inserted inthe neck of the So far as I am aware I am the first to provide a hotwater bottle which may be described is very advantageous for this" use.

.Its form, rigid. construction and the rigid connection of the neck withthe body of the container, permit the latter to be applied andcontrolled bysaid neck and manipu- 'lated as desired. This control ismade ipos .neously by the hot water bottle.

The bottle sible by the fact that the handle is always I cool andreadily handled without liability of discomfort or danger of burning theuser.

In massaging it is desirable to warm the parts to be treated and alsomaintain a cir culation in them" This is effected simulta- In manyinstances it is desired that the human body shall not bear the weight ofthe bottle, but that the heat-"of the latter shall be transmitted to thebody merely by the lying of the bottle against the side of the body.lVhere a' rubber'bottle is em ployed for this purpose the gravitationaleffect of the Water would cause the bottle to distort or collapse moreor less, and as a result but a small portion of the bottle would beavailable for lateral contact with the body. The bottle described hereinwill not collapse, but on the contrary'may he stood up on its edge andpresent a large extent of surface for contact with the body.

The opposite flattened sides'of the bottle Will'always be firmlymaintained in spaced relation by.the staying stud between them. In factthe bottle thus constructed is se strongthatit will sustain the weightof the human body without injury to said bottle.

Rubber bottles do not stand hot temperarules, and users of them areexplicitly causince it used it will cause the rubber to deteriorate andsoon Wear out. However, even it proper caution is taken in this respect,rubber bottles do not stand service, but quickly Wear out and soon leakand frequently cause bad cases of scalding. Rubber has other objections.in that when hot it gives off a damp steamy heat and a very offensiveodor which is intolerable to sick persons or those of delicatesensibilities.

By the bottle described, the above objectionsare overcome, since-themetal container will stand very high temperatures and maintains its heatmuch longer than rubber bottles; it is not liable to leak and does notgive forth adamp heat or any odor.

It will be observed'that the Walls of the body of the hot Water bottleare single, to present outer heat conducting surfaces. The bottle isshown as of an oblate spheroid form, the neck thereof extending rigidlyfrom the rim of the body. It will also'be them rigid connection, presenta rigid structioned not to use too hot Water in them,
